Description

Technical Field

[0001] This utility model relates to the field of crushing equipment technology, and in particular to a crusher tooth plate. Background Technology

[0002] The crusher tooth plate is the core working component of the crushing equipment. It directly contacts the material and withstands impact, compression, and wear. Its crushing structure usually consists of two tooth plates forming a V-shaped crushing chamber. The material is compressed and crushed through the pendulum motion of one of the tooth plates. Therefore, the structural integrity of the tooth plate is crucial to ensuring the stable operation of the crusher. Wear resistance and toughness are the core performance indicators of the crusher tooth plate, and they together determine the service life and crushing efficiency of the tooth plate under complex working conditions. During the crushing process, the tooth plate and the material experience sliding friction, impact wear, and abrasive cutting, causing the tooth crown to gradually wear thin and eventually fail. Although high wear resistance can slow down the wear of the tooth crown, it is more prone to fracture. During the crushing process, large pieces of material or hard impurities (such as iron blocks) may cause instantaneous high-stress impacts on the tooth plate. The higher the toughness of the tooth plate, the higher its ability to absorb impact energy and the less likely it is to fracture, but it is also more prone to wear. Utility Model Content

[0003] In view of the shortcomings of the above-mentioned prior art, this application provides a crusher tooth plate that can simultaneously improve the wear resistance and toughness of the tooth plate, ensure the service life and crushing efficiency of the tooth plate, and has strong practicality.

[0004] To achieve the above objectives, the present invention employs the following technology: A crusher toothed plate includes: a base plate and a crushing assembly.

[0005] The top surface of the base plate has a toothed bar at its center, and the length of the toothed bar is parallel to the length of the base plate. The crushing component includes two jaw plates respectively located on both sides of the toothed bar and detachably connected to the base plate. The top surface of the jaw plate has multiple jaw teeth along its width direction, and the jaw teeth are aligned with the teeth of the toothed bar. The top of the jaw teeth away from the toothed bar has an inclined surface. Multiple rows of reinforcing rods are provided along the width direction below the inclined surface and the horizontal plane of the jaw teeth. There is a gap between the top of the reinforcing rod and the top of the jaw teeth.

[0006] Furthermore, one end of the jaw plate is provided with multiple slots along its width direction, and both sides of the toothed bar are provided with multiple pins along its length direction, the pins engaging in the slots.

[0007] Furthermore, the bottom surface of the jaw plate is provided with multiple threaded grooves, and the base plate is provided with multiple through threaded holes. The threaded holes are aligned with the threaded grooves and screws are inserted to connect the jaw plate and the base plate.

[0008] Furthermore, the axis of the reinforcing rod located below the inclined plane is perpendicular to the inclined plane.

[0009] Furthermore, the lower end of each row of reinforcing bars is connected to a crossbar, and adjacent crossbars are connected by a connecting rod.

[0010] The advantages of this utility model are as follows: the toothed plate is divided into a base plate and a jaw plate. After the jaw plate fails due to wear, breakage or other reasons, only some parts need to be replaced, which reduces the cost of equipment use. A reinforcing rod is implanted under the jaw teeth of the jaw plate to enhance the wear resistance and toughness of the jaw teeth, thereby improving the crushing effect and service life.

[0013] Figure 2 This is a cross-sectional structural assembly diagram of an embodiment of this application. Detailed Implementation

[0014] To make the objectives, technical solutions and advantages of the present utility model clearer, the implementation methods of the present utility model will be described in detail below with reference to the accompanying drawings. However, the embodiments described in the present utility model are only some embodiments of the present utility model, and not all embodiments.

[0015] like Figures 1-2 As shown, this example provides a crusher toothed plate, including: a base plate 1 and a crushing component 2.

[0016] The bottom plate 1 has a toothed bar 11 at its center on the top surface. The length of the toothed bar 11 is parallel to the length of the bottom plate 1. The crushing component 2 includes two jaw plates 21, which are respectively located on both sides of the toothed bar 11 and detachably connected to the bottom plate 1. The top surface of the jaw plate 21 has multiple jaw teeth 22 along its width direction. The jaw teeth 22 are aligned with the teeth of the toothed bar 11. The top of the jaw tooth 22 away from the toothed bar 11 has an inclined surface. Multiple rows of reinforcing rods 23 are provided along its width direction below the inclined surface and the horizontal plane of the jaw tooth 22. There is a gap between the top of the reinforcing rod 23 and the top of the jaw tooth 22. The reinforcing rod 23 is made of alloy and forms an integral part with the jaw tooth 21. Without affecting the original toughness of the jaw tooth 22, it can enhance the wear resistance of the jaw tooth 21 and improve the service life of the jaw plate 21.

[0017] Specifically, the jaw plate 21 has multiple slots 24 along its width at one end, and multiple pins 12 along its length on both sides of the toothed bar 11. The pins 12 are engaged in the slots 24, so that when the jaw plate 21 is installed, the jaw teeth 22 can be aligned with the teeth of the toothed bar 11 one by one, which facilitates installation.

[0018] Specifically, the bottom surface of the jaw plate 21 is provided with multiple threaded grooves, and the base plate 1 is provided with multiple through threaded holes. The threaded holes are aligned with the threaded grooves and screws are inserted to connect the jaw plate 21 and the base plate 1, which also facilitates the replacement of the worn jaw plate 21.

[0019] Specifically, the axis of the reinforcing rod 23 located below the inclined plane is perpendicular to the inclined plane to ensure the enhancement effect on the wear resistance of the jaw teeth 21.

[0020] Specifically, the lower end of each row of reinforcing rods 23 is connected to the crossbar 25, and adjacent crossbars 25 are connected by connecting rods 26, so that the reinforcing rods 23 can be placed in the casting mold when the jaw plate 21 is cast.

[0021] Since the above are merely preferred embodiments of this utility model and are not intended to limit this utility model, it is obvious that those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
